Genshin Impact : Chaos Circuit

To obtain a Chaos Circuit, you need to find and kill Humanoid Ruin Machines over Level 40+. Upon eliminating these automatons, they have a chance to drop Chaos Circuit. Anything above Lvl 40+ also has a chance to drop Chaos Device.

To get Humanoid Ruin Machines to become Lvl 40+, you need your World Level to become World Level 2 or higher. The most efficient WL to farm anything that needs Lvl 40+ is WL 4, as enemies are between Level 42 and 62. This will give you the most consistent enemy Lvl past 40+. Anything below you will find them, but not as often.

To get to WL 4, you need to have completed the following.

• Be on World Level 3
• Be Adventure Rank 35
• Clear Ascension Quest 2

You can only get these from the humanoid Ruin Machines. Killing the Ruin Sentinels you will not get Chaos materials.

These automatons are mostly in the Liyue region, but you can find a few in Mondstadt and Liyue. The fastest way to get around is to use the Waypoints, kill everything in sight, and then move on. The images below are where you can find Humanoid Ruin Machines.
